摘要
采用旋转舟液相外延生长系统获得GaP外延片,由它制得CaP红色发光二极管,其外量子效率可高达10%(在电流密度为1.3A/cm2时).GaP红色发光材料的最佳生长条件如下:在P型熔体内,Zn的摩尔分数为40×10-4,Ga2O3的摩尔分数为10×10-3;在N型熔体内,Te的摩尔分数为8.0×10-5×~10×10-4;P型外延层厚度为50μm左右.
sing a rotating boat system for liquid phase epitaxial growth the GaP epitaxy has been prepared. With the epitaxy a emitting diodes is obtained, its external quantum efficiency may actived at as high as 10% with a current density of 1.3 A/cm2. The optimum groWth conditions are in a P type fuSion Zn concentration is 0.040mol%,Ga2O3 concentration is 0.100mol%, in N type fuSion, Te concentration is 0.008 ̄0.010 mol%, the thi ckness of P type epitaxy is about 50μm.
